The creep compaction behavior of crushed mudstones

2019-3-8 · The crushed rocks are used as a filling material in mined-out areas of underground mining. Compared with the man-made filling materials, the crushed rocks exhibit higher compressibility and lower stability, which may result in instability of surrounding rock and surface subsidence. To study the creep compaction behavior of crushed mudstones, a series of creep tests are conducted. The ...
